Maybe they'll keep the Orcs in UC and make the Wrathgate into a Feat of Strength? Seems like a pretty logical and simple solution to me... <.<;;
And this AFTER i've completed my Loremaster!...ok, Eastern wasn't at all hard, but still.Meh.
Maybe the Humans will recover Undercity and make it as glorious as it was before Arthas came. The Undead could take up a more strengthened position in Northrend, since the bulk of their forces are stationed there according to the Orcish guard in Uc. They could also use it as home for the Worgen, although they will probably stay in Gilneas.
